Title:

RELAY SELECTION ROUTING METHOD AND RELAY SELECTION ROUTING APPARATUS BASED ON DIRECT COMMUNICATION OF TERMINAL

Document Type and Number:

WIPO Patent Application WO/2016/015379

Kind Code:

A1

Abstract:

The present invention provides a relay selection routing method based on direct communication of a terminal. The method is used in a base station. The method comprises: establishing a database of a topological structure of a direct communication terminal on a network side; when a change of the topological structure is detected, updating the database of the topological structure; when a direct communication service request is received, determining a data sending path and a destination relay node corresponding to the direct communication service request according to the database of the topological structure, sender information and receiver information of the direct communication service request and a preset selection principle; and establishing a direct communication data sharing network corresponding to the direct communication service request according to the data sending path and the destination relay node. Correspondingly, the present invention also provides a relay selection routing apparatus based on direct communication of a terminal. By means of the technical scheme, unnecessary signaling overheads caused by broadcasting in an overlarge range when the topological structure is established are reduced, and the timeliness of the database of the topological structure is improved.
